Well, I knew whatever concept you picked it would be awesome, and you don't dissapoint. Loving the gas idea, definately unique so far. If this is just a quick sketch, I really don't want to see when you start adding details. Great work so far.

Hey Ced killer job so far, My first thought however is he seems a bit top heavy, I understand he has the back armor and mechanics to help with balance but I for some reason want to see some sort of stabalizing element on his lower torso (particularily around the feet) just my opinion though. Otherwise top notch.

Nice 'sketch'! But I agree with Warbringerd, the legs don't look as if they would support his torso especially seeing as they are have no real land area touching the ground. Get some solid feet and/or legs in there and I think you are onto something

The small legs definately make his upper body look more powerfull. How about increasing the overall length of the thighs/calves (bring the knees forward a bit, and the ankles backward), and giving the feet a tad wider base. Great start man!....But I expected nothing less.

Aye, that's awesome. I really like the proportions you've got now but I gotta hop on the "feet are too small" bandwagon. Don't want a big fella' like that toppling over. Unless of course, that's his last ditch attack, falling over on the enemy. ;p

I'm torn; the topheavy comments are valid, but the exaggeration emphasize the upper body. I guess I shouldn't care; if nobody said anything, I'd still just be drooling That's awesome looking as is; I can't believe you'll make it better...
